Specification of Letters Patent. y Patented NGV. 3G, 1915.

Application filed September 28, 1914. Serial No. 863,930.

T0 all whom it may concern: c

Be it known thatl, INsHRisri Asi-reim, a citizen of the United States,residing at New Ulm, in the county ofr Austin and State of Texas, haveinvented certain new and useful Improvements in Ventilators, of whichthe following is a specification.

This invention relates to improvements in vventilating-cowls for use onbuildings and the like, and its Objectis to produce aventilator thatwill help to create a draft through the tubular stem, and that at thesame time will serve as a spark arrester.

With the foregoing and other objects in view the invention consists inthe combination and arrangement ofparts to be hereinafter fullydescribed in the following specification, pointed out in the claim andillus-v trated in the accompanying drawings which form a part of saidspecification and yin which- Figure 1` is a side elevation of aventilating cowl constructed in accordance with my invention. Fig. 2 isa top plan of the same. Fig. 3 is an inverted plan. Fig. 4 is a verticalsection. Fig. V5 is a cross section taken on line 5 5 of Fig. 4.

Like reference characters indicate corresponding parts throughout theseveral views.

The reference numeral l designates the tubular stem of I ny improvedVentilating cowl and 2 is a cap arranged to overhangr theV upper end ofsaid stem to which it is secured by angular braces 3. About the upperportion of the tubular stem and cap 2 I provide a cylindrical shell 4,open at the top, formed with a plurality of apertures or perforations 5and provided with an integral perforated base 6, open in the center toadmit the tubular stem to which said base is secured in any suitablemanner. Adja-l cent the upper or openend of the cylindrical shell Iprovide a ring 7 formed with in!A tegral feet 8 by which it is securedto the inner wall of said shell bolts 9, the inner lower edge of the cap2.

'The smoke', Yair and sparks passing up through the tubular stem willstrike the cap 2, the smoke and airbeing deflected thereby and caused topass out under the lower edge out between the cap and the ring 7 vintothe atmosphere. 'Some Vof the sparks will fall back into the tubularstem, some may pass out beneath the cap 2 and fall upon'tlie bot'- tom 6direct, or strike the ring 7 and then fall upon said bottoni, thepossibility of any sparksy escaping frointhe device and causingvdestructive fires is practically m'Z. Y

v What is claimed is A device ofthe type described, including a tubularstem or member. aconical cap having an internal deiecting surface, withits baseoifset from, and positioned somewhat above the upper end of saidstem, angular bracket-like connections between said `cap and stein, andVa cylinder provided with numerous draftgenerating` passagestherethrough the lower end of which cylinder is provided with a basealso having numerous air passages and fixed to said cylinder, the upperend of said cylinder opening upwardly and slightly above said cap ofsaid stem, said cylinder having attached to its inner side an annulardeiiector, said deflector having its inner edge slightly spaced from,and somewhat above the base-edge of said conical cap.
